Variable Description
Effective addition volume of the suppressor solution on
the evaluation criterion.
Total volume (sample solution) in the measuring vessel at
the moment of the measurement of the VMS by calling
the measuring command via the command CALL VMS
at the moment of calibration.
Calibration factor DT. It corresponds to the concentra-
tion of the standard in the measuring vessel for the eval-
uation ratio.
5.6.7.7.21 Absolute standard deviation of the concentration of the suppres-
sor in the sample
Variable name RS.’Command name’.’Substance name’.CONC.ASD
Description Absolute standard deviation of the concentration of the suppressor in the
sample.
Decimal places 0 - 2 - 6
Unit As for concentration of the substance in the sample (see Chapter
